摘要: Three-dimensional (3D) ultrasonic vibration-assisted ELID grinding, which combines 3D vibration-assistance with electrolytic in-process grinding wheel dressing (ELID), is a compound process that designed to achieve high-efficiency precision machining. A force model of was first developed on the basis kinematics single grit particle and verified through experimentation. The surface quality then observed using white light interference profiling. It demonstrated during present investigation approximately 20 %~30 % lower than two-dimensional (2D) grinding. In addition, roughness (Ra) achieved 40 %~50 smoother under 2D ELID, thus can better quality.
